Freshwater Trematodes Sanguinicola (Digenea: Aporocotylidae) in Europe: Distribution, Host Range, and Characteristics of Fish and Snail Infestation (Review)

Abstract

Data on trematode life cycles, fish host distribution, transmission, and fish and snail infection are reported in this review. European freshwater trematodes of the genus Sanguinicola (Aporocotylidae) remain an insufficiently studied group of trematodes. Five species of Aporocotylidae (Sanguinicola armata, S. inermis, S. intermedia, S. volgensis, and S. rutili) in freshwater fish of Europe are described. In addition, they have been found in the water bodies of Central Asia and West Siberia (Ob-Irtysh River basin). The life cycle allowing us to assign the cercariae and adults to a certain species is known only for S. armata, S. inermis, and S. rutili. Trematodes of the genus Sanguinicola are found in 26 fish species assigned to 7 families and 4 orders and 24 gastropod species assigned to 7 families. With few exceptions, the sanguinicolid infection of fish and snails is rather low in the natural water bodies.

Molecular identification of trematode parasites infecting the freshwater snail Bithynia siamensis goniomphalos in Thailand

“…Zhokhov et al . (2021) have summarized records of Sanguinicola Plehn, 1905 from snails, including Bithynia , mostly in Europe.…”

Underreported and taxonomically problematic: characterization of sanguinicolid larvae from freshwater limpets (Burnupiidae), with comments on the phylogeny and intermediate hosts of sanguinicolids

“…A vast majority of studies on sanguinicolid larval stages are from Europe, USA and Australia, with minimal reports from Asia, South America and Africa. The intermediate hosts of sanguinicolids from Europe have been presented in detail by Zhokhov et al (2021). The data show that snails from 7 different families (Bithyniidae, Lithoglyphidae, Lymnaeidae, Melanopsidae, Neritidae, Planorbidae, Valvatidae) are intermediate hosts for sanguinicolids (Zhokhov et al, 2021).…”

“…However, 28S rDNA phylogenetic analyses of all the available sequences of marine and freshwater fish blood flukes revealed 5 distinct lineages (Cutmore et al, 2023). Consequently, based on morphological characteristics and genetic data, revised fish blood flukes into 5 families: Aporocotylidae Odhner, 1912;Sanguinicolidae Poche, 1926;Chimaerohemecidae Yamaguti, 1971; Acipensericolidae Elopicolidae Warren and Compared with their marine counterparts, blood flukes of freshwater fish are understudied (Zhokhov et al, 2021). Species of Sanguinicolidae and Acipensericolidae predominantly infect freshwater fishes .…”
